table contact has no column named time (code 1)

I have this error: table contact has no column named time (code 1): , while compiling: INSERT INTO contact(time,day,status) VALUES (?,?,?) at android.database.sqlite.SQLiteConnection.nativePrepareStatement(Native Method please help me if you know the solution.

my code is :

public  void onCreate(SQLiteDatabase db)
{
            db.execSQL("CREATE TABLE " + TABLE_CONTACTS + "(" + KEY_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + KEY_TIME + " TEXT," + KEY_STATUS + " TEXT," + KEY_DAY + " TEXT)");

}

and I add data in this way:

     button6.setOnClickListener(new View.OnClickListener() {
       @Override
        public void onClick(View v) {

           String A="aa";
           String B="bb";
           String C="cc";

           Contact contact = new Contact(0,A, B ,C);

           try {
               dbHandler.createContact(contact);
           } catch (Exception e) {                


               Log.e("ERROR", "ERROR IN CODE: " + e.toString());
           }

        });
